Yes, It seems I´m the only one who thinks about going from JDM FD to USD FD, hehe

It is just a mind at the moment, but I think when my ITR is turboed I want a faster car. I realy think the USDM final drive makes me not slower, cause I can make a bit more boost in 1st and 2nd gear, cause of the longer engine load.

I know a punch of people have installed a JDM fd and I wonder what you do with you stock fd. I guess you have it somewhere in the garage or so

What do I need beside the 4.400 gear. Any bearings and /or other gears?

Who can help me out.

Don't forget about the 4.20 final drive that the LS tranny has in it.

I guess you would need the same parts as the 4.785 install would require... https://honda-tech.com/zerothread?id=119053

-who wished he had a 4.785 for sale...

 

Thanks.

But I don´t get it exactly if I only need this 4.400 gear or do I need some parts beside the fd like shafts, etc. to make a complete tranny conversation to 4.400.

I want to keep my stock 1, 2, 3, 4 and 5th gear.

Common`anyone has to know.

oh yeah, how much would such an convert cost, when I take the parts used? Of course in good shape

Looks like 6 pieces are used in the 4.785 conversion.
-2 needle bearings
-final drive ring
-final drive pinion
-a gear of some sort
-and the item in the little bag near the bottom (middle) of the picture

You will be able to keep your 1st thru 5th.

Not sure how much to perform the swap. Most any good transmission place should be able to perform the work.

I meant what can someone charge me for the used parts.

Somebody knows the exact names of this 6 parts?

What is a gear of some sort?

You'll need a :

USDM countershaft
USDM first gear
USDM FD (4.4)
2 needle bearings (they go between the shaft and first gear)

At least thats what I took out when I installed my ATS, so I assume it's what you need .

 

Thanks

Can you explain me, why I would need a USDM 1st gear? The ratio of 3.230 is the same on JDM and USDM spec.

Do you have those parts for sell?

 

I sold my counter shaft, 4.4 fd, and bearings for 100 bux. Yea I know I could have gotten more for it, but oh well, I helped out a fellow R owner.

 

The gear ratio is the same but the countershaft is a different diameter, so the JDM gear wont fit on a USDM countershaft and vice versa.

 

I know I´m not a tranny expert (not yet) but why does then 2nt-5th gear fit? just confused

 

If you look at a pic of the countershaft, each gear has different splines that it fits on, 1st gear is the only different one, the rest are the same between USDM and JDM.

 

I've got a slightly used complete set.

 

check your PM

 

I'll straight up trade you my 4.4 for your 4.785..... Used less than 10k miles.....
